Embodiment
Explain some embodiment in the embodiment of the invention with utilizing the example that electricity consumption is controlled.Yet, should be noted that the present invention can be applicable to the use of the energy of any kind is controlled, wherein these energy not only comprise electric power, also comprise the energy such as other kind of liquid energy and gaseous state energy etc.
Imagination is carried out the control to the energy use according to the application in the territory.The territory is made up of a group node.Node in the territory can comprise: energy consumption node (EN) is used for consumed energy to carry out expectation function; Coordinator node (CN) is used to coordinate the energy consumption of EN in the territory; And pseudo-energy consumption node (PN), its actual CN of being but pretend in the territory as EN, and be used to coordinate belong to the energy consumption of the EN in another territory.Can utilize the node of any amount that is used for common administration, region, time, law or political interest or purpose to come field of definition.Family can defined node be such as the electric power of air-conditioning and refrigerator etc. and the territory of combustion gas household electrical appliance.The territory can define by comprising the geographic area of a plurality of families as node.The territory can define by comprising the city of incity, city factory as node, perhaps defines by comprising the country of the interior city of country as node.
Fig. 1 illustrates the synoptic diagram of expression classical domain.In Fig. 1, the territory comprises a CN 1 and three EN 2-1,2-2 and 2-3.As Fig. 2, illustrate, CN and EN carry out independent task in the territory.CN 1 carries out overall strategy, and wherein according to this strategy, CN 1 produces with the energy of EN 2 and uses relevant strategy.EN 2 carries out the strategy that receives separately, wherein according to this strategy, and EN 2 its energy consumptions of each Self Control.Strategy to EN 2 is designed to realize that through carried out this strategy by the EN in the territory 2 optimum capacity whole in the territory uses.
As the purpose and the function of machine, EN 2 is designed to carry out function through consumed energy.Can consider through carrying out the result that expectation function obtained and estimate the EN 2 realization energy fluences that this function consumed.The present invention introduces in order to quantize the numerical standard of user to the result's who obtains according to the function of being carried out satisfaction.One embodiment of the present of invention are introduced the satisfaction to the result of quantitative definition, estimate the energy fluence that is consumed thus.In normal operation range, be generally following situation: the energy that allow to consume is many more, and attainable performance is high more and obtainable satisfaction to the result is high more, and uses when being limited when energy, and the satisfaction that is directed against the result of acquisition is lower.Therefore, there is the balance relation between this result's the satisfaction in order to realize the energy fluence that the result consumes and to be directed against.In one embodiment of the invention, come quantitative definition in order to realize the energy fluence that the result consumes and to be directed against the balance relation between this result's the satisfaction by each EN 2 distinctive balance functions.
In one embodiment, use the enquiry data of collecting from a large amount of crowds to define satisfaction.Enquiry data is used to derive and is used to predict that people are directed against the generic function how result's satisfaction changes along with results change.Note that the objective standard of utilizing the defined satisfaction of enquiry data can be provided for estimating satisfaction, but possibly can't reflect specific user individual's actual satisfaction exactly.Therefore, in one embodiment of the invention, at first utilize enquiry data to define satisfaction, revise according to the comfort of individual subscriber to result's behavior through monitoring user subsequently.In one embodiment, EN 2 is designed to receive from user's the complaint and the history of the complaint that recording user proposed.Then, EN 2 analyzes should history and upgrade satisfaction, is directed against result's actual satisfaction so that this satisfaction can reflect the user exactly.In another embodiment, distribute based on the complaint relevant and upgrade satisfaction with the result.Because the balance function is based on satisfaction, therefore when satisfaction was revised, the balance function was also revised.
Expect that balance function used in the present invention is peculiar for 2 of each EN.Usually, different types of EN 2 must have different balance functions.Because their installation site, installation purpose and/or operating environment maybe be different, even the EN of identical type 2, also expection has different balance functions.Although these balance functions are that 2 of each EN are peculiar, these balance functions can compare each other.In the present invention, can compare, define satisfaction with all EN 2 shared quantitative manner in order to make these balance functions.
CN 1 carries out overall strategy, and wherein according to this strategy, CN 1 uses the balance function from EN 2 to produce the strategy to EN 2.This overall strategy is action plan strategy, that comprise target and process that produces to EN 2 in order to guiding CN 1.Producing strategy according to overall strategy when realizing the maximum energy-saving in the territory, CN 1 uses from the balance function of EN 2 to explore each EN energy fluence 2 places, that consumed and to the well balanced between energy consumption result's the satisfaction.Strategy to EN 2 also is to make during operation with energy in order to guiding EN 2 using relevant action plan decision, that comprise target and process.Overall strategy can guide CN 1 when producing to each EN 2 tactful, to distribute different priority to each EN 2.For example, suppose that EN 2 is commercial undertakings.If EN 2-1 is a Business office, then the required level of power consumption of this Business office can be traded off.Yet if EN 2-2 is a hospital, the required level of power consumption of this hospital can not be traded off.
In the present invention, CN 1 can produce strategy by Fixed Time Interval.In one embodiment, for example, CN 1 generation in per 24 hours is strategy once.When arriving the time that produces New Policy, CN 1 request EN 2 is sent to CN 1 with their balance function.Should avoid short relatively frequent requests of the time interval, because this frequent requests can increase the calculated load of node and the communication system that is connected these nodes.EN 2 can trigger CN and produce the strategy to the EN in the territory under the situation that need not to wait for from the request of CN 1.When being triggered by EN, CN 1 weighs functions to produce and the distribution New Policy to EN 2 requests.CN can begin strategy and produce processing when receiving new overall strategy.When the EN that CN can also when finding that new EN adds the territory, perhaps be connected when discovery no longer worked in the territory, the beginning strategy produced processing.
Might consume and compare more energy according to the expection energy of strategy, or might consume when comparing energy still less according to the expection energy of strategy when EN 2 dopes, this EN 2 is to CN 1 request New Policy.Suppose the operating environment deterioration around the EN 2, and EN 2 forecast consumptions with compare more energy carrying out the energy that allows to consume during strategy in carrying out.When EN 2 doped this situation, this EN 2 can ask the loose strategy of looking for novelty to consume more multipotency to allow EN 2.On the other hand; EN 2 forecast consumptions are compared energy still less with the energy that allows to consume when the implementation strategy if the operating environment around the EN 2 is improved; The deflation strategy that can please look for novelty to CN 1 of EN 2 then possibly need multipotency more to come other EN 2 of implementation strategy so that excess energy is dispensed to.
Fig. 3 illustrates the example communication that exchanges between the CN in the territory and EN according to an embodiment of the invention.CN 1 is connected via wired communication path or wireless communications path with EN 2.CN 1 regularly for example every day, weekly or every month to EN 2 broadcasting instructions signals.Then, EN 2 sends back to CN 1 with their balance function.CN 1 uses the balance function that receives to produce New Policy, and these New Policies are sent to EN 2 respectively.CN 1 can be when receiving new overall strategy the broadcasting instructions signal.
To carry out the second best plan slightly out-of-date and when needing New Policy when EN 2 is judged as; For example might consume when comparing more energy or might consume energy still less with the expection energy when carrying out this strategy when EN 2 dopes, EN 2 can send request signal (Fig. 3) to CN 1.As response, CN 1 broadcasting instructions signal is to weigh functions to EN 2 requests.In one embodiment, EN 2 sends report by the short relatively time interval to CN 1 separately.This report for example can comprise the rate of energy dissipation of the EN that sends.It is the energy consumption nodes of working in the territory that this report is used for sending the EN 2 that reports to CN 1 notice.CN 1 has the registration form of the EN 2 in the work in the registration territory.Keep this table, so that as CN 1 when the new EN of registration does not receive report from this table, CN 1 thinks that this EN 2 has just added the territory.Then, CN 1 should be registered in the table by new EN, and initiates strategy generation processing through command signal being broadcast to all registered EN 2.On the other hand, if CN 1 fails to receive report from registered EN 2 in the section at the fixed time, then CN 1 thinks that this EN no longer works in the territory.Then, CN 1 deletes this EN 2 from registration form, and initiates strategy generation processing through command signal being broadcast to registered EN 2.
Fig. 4 illustrates another embodiment of the present invention.Node is connected via wired passage path or wireless communications path.Three territories in Fig. 4, have been formed.First territory (territory A) comprises CN 1A, pseudo-energy consumption node (PN) 1B and PN 1C.As stated, pseudo-energy consumption node is coordinator node (CN) but pretends as energy consumption node (EN).Second territory (territory B) comprises PN 1B and three EN 2B-1,2B-2 and 2B-3.The 3rd territory (territory C) comprises PN 1C and four EN 2C-1,2C-2,2C-3 and 2C-4.In the B of territory, PN 1B produces the strategy to these EN based on the balance function of EN 2B-1,2B-2 and 2B-3.EN 2B-1,2B-2 and 2B-3 carry out these strategies, and under these tactful guidances, realize that B whole optimum capacity in territory uses.Equally, PN 1C produces EN 2C-1,2C-2,2C-3 and the performed strategy of 2C-4, realizes that thus the optimum capacity of territory C uses.
Fig. 5 is illustrated in communicating by letter of exchanging between CN 1A and PN 1B and the PN 1C.CN 1A by fixed intervals for example every day, weekly or every month to PN 1B and 1C broadcasting instructions signal.As response, PN 1B and PN 1C are sent to CN 1A with their balance function.Use these balance functions, CN 1A produces the overall strategy to PN 1B and PN 1C.CN 1A can be when receiving new overall strategy the broadcasting instructions signal.Through sending request signal to CN 1A, PN 1B or PN 1C can ask CN 1A to produce new overall strategy when needing New Policy.PN 1B and PN 1C send report by fixed intervals to CN 1A, so that PN 1B and 1C keep being registered in the registration form of CN 1A.Through the report that supervision is imported into, whether CN 1A can find to have new node to add territory A, and perhaps whether PN 1B or PN 1C do not work in the A of territory.In these cases, CN 1A can the broadcasting instructions signal.
Fig. 6 illustrates another embodiment of the present invention.Two territories (territory D and E) in Fig. 6, have been formed.Territory D comprises CN 1D, three EN 2D-1,2D-2 and 2D-3 and PN 1E.Territory E comprises PN 1E and two EN 2E-1 and 2E-2.CN 1D receives the balance function and produces the strategy to them from three EN 2D and PN 1E.EN 2D and PN 1E carry out these strategies, realize that thus the optimum capacity of territory D uses.Strategy to PN 1E is an overall strategy, and wherein PN 1E carries out this overall strategy, so that use the balance function from EN 2E-1 and EN 2E-2 to produce the strategy to these EN.EN 2E-1 and EN 2E-2 carry out these strategies, realize the optimum capacity consumption in the E of territory thus.
Shown in Fig. 4 and 6, two territories can be via pseudo-energy consumption node overlapping.Formative region dynamically thus, however because the processing of in the territory, carrying out is closed in this territory, and the generation of the strategy in a territory need not to consider other the energy that overlapping territory consumed, it is simple therefore to remain on the processing of carrying out in the territory.Through using the combination of Fig. 1, the example shown in 4 and 6, can define the territory of all size with overlap mode.
In above example, node is coordinator node (CN) or energy consumption node (EN).Node can be that energy provides or generate node.Energy generates node can be mounted in solar panel or the generating plant of utility company's operation in the family.
Fig. 7 A is the synoptic diagram that the representative functional module of energy consumption node (EN) 2 is shown.Communicator 7-1 is configured to communicate via wired communication path or wireless communications path and coordinator node (CN) 1 and other EN 2.Can utilize the communication protocol of any type to carry out the communication between CN 1 and the EN 2.If communicator 7-1 is a wireless communicator, then preferably use the long relatively low-power wireless module of communication range.Energy converter 7-2 is configured under the control of controller 7-3, will become such as the energy conversion of electric power etc. the energy of other type.Shown in Fig. 7 B, controller 7-3 comprises CPU and internal storage and external memory storage, wherein internal storage and external memory storage for example store CPU in order to carry out its expectation function executable program.Energy converter 7-2 can be machine or the device of consumed energy with any type of operation.For example, if EN 2 is air-conditionings, then energy converter 7-2 becomes mechanical energy so that the motor of the compressor operating of air-conditioning with power conversions.If EN 2 is well heaters, then energy converter 7-2 is the heating element that power conversions is become heat.In Fig. 7 A, energy converter 7-2 is the part of EN 2.Yet energy converter 7-2 can adopt following form: energy converter 7-2 conduct is with EN 2 physical separation but the equipment that under the control of EN 2, carries out work.

Policy store 7-6 is configured to store the strategy that the CN 1 the territory under EN 2 sends.Controller 7-3 carries out should strategy, wherein according to this strategy, and the energy consumption of controller 7-3 control energy converter 7-2.The balance function of balance function memory 7-7 record EN2.Controller 7-3 prepares to weigh function based on the recorded information among the operation history storer 7-5.Can show the balance function with arbitrary form such as mathematical equation or table etc.
The operation of EN 2 can be categorized into two processing usually.A processing is that Autonomous Control is handled.Another processing is to upgrade the balance function and will weigh the processing that function is sent to CN 1.At above-mentioned moment place, the CN 1 in the territory of communicator 7-1 under the EN 2 receives strategy.Then, with this policy store in policy store 7-6.In Autonomous Control was handled, controller 7-3 carried out the strategy that receives, and wherein should make the decision relevant with the operation of energy converter 7-2 by strategy guide controller 7-3.Note that EN 2 of the present invention is not that only obey passively should strategy when implementation strategy, but independently take action to explore better course of action by means of the balance function.This balance function controller 7-3 obtains well balanced between energy fluence that energy converter 7-2 consumes and the result's that realized to energy converter 7-2 satisfaction.In one embodiment, strategy comprises one target higher limit in the operating parameter target upper limit amount such as the consumable energy of energy converter 7-2 etc., energy converter 7-2.When carrying out this strategy; Under by the situation that is stored in the balance function among the balance function memory 7-7; Controller 7-3 is attempting under energy consumption with energy converter 7-2 is restricted to situation about setting the goal below the upper limit amount, explore energy fluence that energy converter 7-2 consumes and the result's that realized to energy converter 7-2 satisfaction between well balanced.
Controller 7-3 is upgrading the balance function when CN 1 receives command signal.As stated, the result of balance function representation energy consumption and to the relation between this result's the satisfied program.Controller 7-3 upgrades the satisfaction in the balance function.Certainly, people are different to same result's evaluation.Therefore, it is peculiar that satisfaction is looked at as individual consumer institute.The user of controller 7-3 analyzing stored in operation history storer 7-5 complaint, thus and make the individualized satisfaction of user that reflect more exactly of satisfaction to the result.In one approach, upgrade satisfaction based on the distribution of the complaint relevant with the result.
Fig. 8 A is the synoptic diagram that the functional module of CN 1 or pseudo-energy consumption node (PN) is shown.CN 1 has communicator 8-1, wherein communicator 8-1 be configured to CN 1 under the territory in EN 2 communicate.If coordinator node is PN, then communicator 8-1 can communicate with another CN 1 in another territory.Communicator 8-1 communicates via wired communication path or wireless communications path, and under the situation as wireless communicator, preferably has the long relatively low power communication module of communication range.Timer 8-2 carries out timing triggering controller 8-3 by fixed intervals, thereby initiates to be used to produce the processing to the strategy of EN 2.Shown in Fig. 8 B, controller 8-3 comprises CPU and internal storage and external memory storage, wherein internal storage and external memory storage for example store CPU in order to realize desired function executable program.
The balance function that EN 2 in the territory of balance function memory 8-4 storage under the CN 1 receives.Then, the balance function that controller 8-3 will receive is merged into overall balance function, and should totally weigh function and be stored among the overall function memory 8-5.Should the whole balance function in overall balance function representation territory.Overall strategy storer 8-6 storage is from CN 1 (referring to Fig. 4 and the 6) overall strategy that the operator imported that send or CN 1 on upper strata.Controller 8-3 carries out this overall strategy, and wherein according to this overall strategy, controller 8-3 uses the overall balance function that is stored among the overall function memory 8-5 to produce the strategy to the EN in the territory 2.
Fig. 9 illustrates the strategy that CN 1 carried out to produce the process flow diagram of handling.In step 901, the controller 8-3 of the CN 1 that is triggered by timer 8-2 is via the EN 2 broadcasting instructions signals of communicator 8-1 in the territory.As response, EN 2 is sent to CN 1 with their balance function.In step 902, the balance function that controller 8-3 will receive is stored among the balance function memory 8-4.In step 903, the balance function that controller 8-3 will receive is merged into overall balance function and should totally be weighed function and is stored among the overall function memory 8-5.In step 904, controller 8-3 carries out and is stored in the overall strategy among the overall strategy storer 8-6, and wherein according to this overall strategy, controller 8-3 uses the overall balance function among the overall function memory 8-5 to produce the strategy to EN 2.Then, in step 905, controller 8-3 is sent to EN 2 with the strategy that is produced respectively via communicator 8-1.
Figure 10 illustrates one that adopts in the benefit of the present invention.Shaded stripe is illustrated in the strategy that carries out at the CN place and produces processing.In Figure 10, took place once in per 12 hours to the generation of the strategy of EN.Although strategy produces the length of handling and depends on the quantity of the EN that is connected and the computing power of CN, expect that this length is a few minutes to arrive dozens of minutes.In Figure 10, should activity in per 12 hours, only take place once.In the present invention, when CN is sent to the EN that is connected with strategy, the task termination of this CN, and this CN do not work basically, up to next strategy produce handle till.EN carries out these strategies, and wherein according to these strategies, EN independently controls their energy consumption.Therefore, use the load of control system middle controller to compare with the conventional energy of using at the energy of paying close attention to and control all EN that do not have the Autonomous Control ability usually, the load of this CN is very light.In addition, take place once in per 12 hours with communicating by letter of EN.Therefore, the load of communication system is also very light.
Figure 11 illustrates the energy that applies the present invention to one group of air-conditioning and uses the embodiment that controls.In Figure 11, a remote controllers 11-0 and three air-conditioning 11-1,11-2 and 11-3 constitute the territory.Air-conditioning 11-1,11-2 and 11-3 are the energy consumption nodes (EN) in the territory.Remote controllers 11-0 is the coordinator node (CN) in the territory.In the present embodiment, remote controllers 11-0 is the remote controllers of air-conditioning.Nowadays, the remote controllers of air-conditioning are the intelligent controllers that inside has microcomputer, and this microcomputer is enough advanced, thereby can carry out the required calculating of embodiment of the present invention.Remote controllers 11-0 and air-conditioning 11-1,11-2 and 11-3 via low power radio network each other wireless connections with at switched communication between this.In the present embodiment, energy use amount every day of controller 11-0 control air-conditioning 11-1 and 11-2, thereby produced once strategy in per basically 24 hours.According to these strategies, air-conditioning 11-1 and 11-2 independently control in 24 hours their energy consumption, thereby the total power consumption of accumulative total in 24 hours is restricted to below the aim parameter.Controller 11-0 produce New Policy and air-conditioning 11-1 and 11-2 independently control the time interval of their energy consumption can be for such as per 12 hours, per 24 hours, per two days or the arbitrary time span that waits weekly.As stated, should avoid the time interval, because these short time intervals have increased the calculated load of controller 11-0 and air-conditioning 11-1 and 11-2 such as the weak point of per 5 minutes or per 10 minutes etc.
Figure 12 is the block diagram that the structure of controller 11-0 is shown.This controller comprises two modules.A module is tactful generation module 12-1.Another module is Autonomous Control initiation module 12-2.Controller 11-0 has timer 12-3.Timer 12-3 is according to schedule time table trigger module selector switch 12-4.Under situation about being triggered by timer 12-3, module selector switch 12-4 judges it is to start tactful generation module 12-1 or start Autonomous Control initiation module 12-2.If arrived the time that starts Autonomous Control initiation module 12-2; Then module selector switch 12-4 is sent to Autonomous Control requester 12-5 with enabling signal, and wherein Autonomous Control requester 12-5 carries out the strategy to their operation via transmitter 12-6 indication air-conditioning 11-1,11-2 and 11-3.Automatically control request device 12-5 has air-conditioning and the table of their operating conditions separately in working in the registration territory.Whether an expression air-conditioning in these operating conditions carries out according to control of the present invention.The user possibly expect to control according to the present invention some air-conditionings in these air-conditionings, but the air-conditioning that possibly not expect other is as the part in this control group.Autonomous Control requester 12-5 optionally is sent to command signal and is registered as the air-conditioning that carries out according to control of the present invention.
If to starting time of tactful generation module 12-1, then module selector switch 12-4 is sent to balance function request device 12-7 with enabling signal.Balance function request device and Autonomous Control requester are shared the registration form that is used for registering the air-conditioning of work in the territory.Under by situation about triggering from the enabling signal of module selector switch 12-4, balance function request device 12-7 is sent to command signal (referring to Fig. 3 and 5) air-conditioning of being registered, is air-conditioning 11-1,11-2 and 11-3 (referring to the step 901 of Fig. 9) via transmitter 12-6.In the present embodiment, under situation about being triggered by timer 12-3, per 24 hours of module selector switch 12-4 is sent to balance function request device 12-7 once with enabling signal.If the communication speed between controller 11-0 and air-conditioning 11-1,11-2 and the 11-3 is slow; Then because communication slowly makes the resource of air-conditioning shift from the common air-conditioning function of controlling them; Therefore preferably; Shown in figure 13, timer 12-2 is set to when air-conditioning is not all worked, start balance function request device 12-7 during for example at 12:00am.If communication speed is fast, trigger balance function request device 12-7 under the situation that any air-conditioning that then timer 12-2 can be in these air-conditionings or all air-conditionings are being worked.If communication speed is slow, then timer 12-2 can store the timetable of time period shown in figure 13, that air-conditioning work is shown.
In one embodiment, the air-conditioning quilt in the work is designed to by fixed intervals, for example per a few minutes are sent once notice to controller 11-0, wherein weighs function request device 12-7 and receives this notice via receiver 12-8.This notice can comprise the rate of energy dissipation of the air-conditioning that sends, and is used for working in the territory to the air-conditioning of balance function request device 12-7 notice transmission notice.Use is from these notices of air-conditioning; Balance function request device 12-7 keeps registration form; So that when balance function request device 12-7 when new air-conditioning receives notice, this balance function request device 12-7 should be registered in the table by new air-conditioning, and if weigh function request device 12-7 and fail to receive notice at the fixed time section from registered air-conditioning; Suppose that then this air-conditioning no longer works in the territory, balance function request device 12-7 with this air-conditioning from list deletion.Except that the regular timetable of timer 12-3 institute timing, when new air-conditioning is added in the table, or with registered air-conditioning when this table removes, balance function request device 12-7 is sent to command signal in the air-conditioning of being registered.The quantity of the air-conditioning in the territory in the work increases or reduces makes the implementation second best plan slightly out-of-date, thereby triggering for generating is to the New Policy of the air-conditioning in the work.
Be back to Figure 12, receiver 12-8 receives balance function (step 902 of Fig. 9) from air-conditioning, and the balance function that will receive is stored among the balance function memory 12-9.Wait extremely received the balance function from all air-conditionings after, the balance function that balance function memory 12-9 will receive provided to tactful generator 12-10.Balance function memory 12-9 can wait for the schedule time, and only is provided to the balance function that this schedule time receives till expiring.So, balance function memory 12-9 can avoid continuing to wait for the balance function from the air-conditioning of no longer working in the territory.
Figure 14 illustrates the sample table of one the balance function that is used for defining air-conditioning 11-1,11-2 and 1-3.Should be noted that table shown in Figure 14 only is of example who is used for defining the balance function of air-conditioning, and can show this balance function with other form such as equality etc.In table shown in Figure 14, left end list out the room temperature that air-conditioning setting and this air-conditioning are realized thus.Thereby, be the energy consumption result of this air-conditioning by the room temperature of air-conditioning setting and realization.From the secondary series of right-hand member the poor of the most desirable room temperature (25 degree) and the temperature that air-conditioning is provided with is shown.When the temperature to the air-conditioning setting is 28 when spending, result's (room temperature is 28 degree) with respect to the most desirable room temperature deviation 3 degree.
Right-hand member list out the satisfaction that is directed against the room temperature that is realized.Thereby this expresses set temperature and to the relation between the satisfaction of set temperature.This satisfaction is the function of the temperature difference.As stated, when the operation of air-conditioning begins, can draw the satisfaction shown in these row, revise to the satisfaction of the temperature difference according to the user subsequently according to enquiry data.In this table, room temperature is 25 degree values of being endowed " 100 ", and the surveyee that this expression number is maximum is that 25 degree feel comfortably cool to room temperature.Thereby, according to table shown in Figure 14, suppose that 25 degree are the most desirable room temperatures of people.The number that feels comfortably cool rises with respect to ideal temperature along with room temperature and reduces.If it is 28 degree that air-conditioning is provided with temperature, then the satisfaction to result's (room temperature is 28 degree) drops to 70.
Illustrate to be expected at from the secondary series of left end the energy that temperature will be saved in following 24 hours respectively is set.When air-conditioning being provided with temperature is 28 when spending, and compares with keeping the required energy of ideal temperature (25 degree), is expected at operating period of one day will save the energy of 0.9kWh.Table shown in Figure 14 also illustrates and temperature is set and this is provided with the relation between the savable energy fluence under the temperature.Thereby this table provides and has been used for the converse routine that temperature transition becomes savable energy fluence when being provided with these temperature is set.This is below converse routine ordinary representation: temperature is compared with the most desirable room temperature and is set to highly more, and then the energy that will save of expection is many more.In the present embodiment, temperature is set and these forms that table of the relation between the savable energy fluence under temperature is set provide converse routine to illustrate.This converse routine can be an equality of describing this relation.In addition, in the present embodiment, in the table that the balance function is shown, this converse routine is provided by EN 2.In one embodiment, this converse routine is arranged among the CN 1 in advance.In this embodiment, temperature, the temperature difference and satisfaction are set from expressing of sending of EN.
Return Figure 12, after balance function memory 12-9 receives the balance function, tactful generator 12-10 produces the strategy to air-conditioning.Suppose shown in figure 15ly, tactful generator 12-10 only receives the balance function from air-conditioning 11-1 and 11-2, and air-conditioning 11-3 fails to send in the given time its balance function.Strategy generator 12-10 thinks that air-conditioning 11-3 can't suitably work, and begins to produce the strategy to air-conditioning 11-1 and 11-2.Because the user of air-conditioning 11-1 and 11-2 possibility is different thereby supposition has different satisfactions, and the operating environment of these air-conditionings maybe be different, and therefore balance functions shown in figure 15, these air-conditionings should differ from one another naturally.
When producing to air-conditioning 11-1 and 11-2 tactful, at first, tactful generator 12-10 searches the overall strategy that will carry out in overall strategy storer 12-11.Suppose that the overall strategy that is stored among the storer 12-11 comprises the interior energy that is consumed of representative domain will be saved " 0.5kWh at least " altogether in 24 hours target.Then, tactful generator 12-10 is merged into single table shown in figure 16 with the table of Figure 15, wherein these single all combinations of expressing the temperature of on the table to air-conditioning 11-1 and 11-2, listing.In table shown in Figure 16, be illustrated as the summation of the energy that expection that each line display in the row of " can save gross energy " lists will save in the same delegation to air-conditioning 11-1 and 11-2.Be illustrated as summation that each row in the row of " total temperature difference " is illustrated in the temperature difference of listing in the same delegation to air-conditioning 11-1 and 11-2.Each row that is illustrated as in the row of " satisfaction " illustrates satisfaction of using total temperature difference to derive according to function.Then, tactful generator 12-10 is arranged in table shown in Figure 17 with each row in the table shown in Figure 16, and wherein the less row of the value of total temperature difference appears at the top (referring to the step 903 of Fig. 9) of this table.Table shown in Figure 17 is represented to the whole overall balance function in territory.
Strategy generator 12-10 uses table shown in Figure 17 to produce the strategy to air-conditioning 11-1 and 11-2.In order to serve the user of air-conditioning better, these air-conditionings should attempt realizing obtaining from the user room temperature of higher satisfaction.Yet overall strategy comprises expression and air-conditioning 11-1 and 11-2 and keeps the target that the required energy of the most desirable room temperature (is 25 to spend and be 26 to spend for air-conditioning 11-2 for air-conditioning 11-1) is compared, in 24 hours, should be saved the energy of 0.5kWh altogether.Note that this hypothesis of ideal temperature that must room temperature be set to them based on the user explains present embodiment.Thereby the overall strategy of present embodiment requires air-conditioning 11-1 and 11-2 and in order to keep the most desirable room temperature the energy of consumption is compared, total power consumption is restricted to the 0.5kWh that in 24 hours, descended altogether.
Strategy generator 12-10 searches the row that the gross energy saved that is equal to or greater than 0.5kWh is shown in top from this table in table shown in Figure 17 to the bottom.Then, in these row that find, tactful generator 12-10 selects to illustrate the row of high satisfaction.In Figure 17, there are two row to meet the requirements.Such row illustrate expection saved the energy of 0.5kWh altogether and realized satisfaction be 85, be 26 degree and be the combination of 26.5 degree to air-conditioning 11-1 to air-conditioning 11-2.Another such row illustrate expection saved the energy of 0.6kWh altogether and realized satisfaction be 85, to air-conditioning 11-1 be 25 the degree and to air-conditioning 11-2 be 27.5 the degree combination.Because back one combination can utilize less energy to realize identical satisfaction, therefore tactful generator 12-10 selects back one combination (be 25 degree and be 27.5 degree to air-conditioning 11-2 to air-conditioning 11-1).Then, tactful generator 12-10 prepares the strategy (referring to the step 904 of Fig. 9) to air-conditioning 11-1 and 11-2.Strategy to air-conditioning 11-1 comprises that target temperature is 25 degree.Strategy to air-conditioning 11-2 comprises that target temperature is 27.5 degree.Then, these strategies are provided to strategy report device 12-12, wherein strategy report device 12-12 is sent to air-conditioning 11-1 and 11-2 via transmitter 12-6 respectively with these strategies.The room temperature that replacement will be kept can comprise the target energy amount that will save (be 0kWh and be 0.6kWh to air-conditioning 11-2 to air-conditioning 11-1) to the strategy of air-conditioning 11-1 and 11-2.
Figure 18 is the block diagram that the functional structure of air-conditioning 11-1 is shown.Air-conditioning 11-2 has identical structure with 11-3.This air-conditioning comprises two modules.A module is Autonomous Control module 18-1.Another module is balance function update module 18-2.At first, receiver 18-3 slave controller 11-0 receives strategy.With the policy store that receives in policy store 18-5.Then, when receiver 18-3 slave controller 11-0 received Autonomous Control initiation signal, module selector switch 18-4 started Autonomous Control module 18-1.Module 18-1 has policy engine 18-6, and wherein read strategy and carry out from policy store 18-5 should strategy for policy engine 18-6, wherein according to this strategy, and the operation of policy engine 18-6 control air regulating device 18-7.Policy engine 18-6 receives service data by fixed intervals from conditioner 18-7.This service data comprises that rate of energy dissipation or the conditioner of conditioner are in the amount of power of nearest interval internal consumption and the duration of this conditioner work.This service data also comprises the temperature data of the room temperature at the interval that expression is nearest.Policy engine 18-6 will be stored in from the service data of conditioner 18-7 among the operation history storer 18-8.Thereby, history, the duration of conditioner work and the history of room temperature of the rate of energy dissipation of operation history storer 18-8 record conditioner 18-7.Through the rate of energy dissipation that writes down from the time that receives a last strategy is carried out integration; Policy engine 18-6 calculates from receiving the energy total amount that last one tactful conditioner 18-7 has consumed, and this energy total amount is stored among the operation history storer 18-8.According to the energy total amount that conditioner consumed and the total duration of conditioner work, policy engine 18-6 calculates the average energy consumption of conditioner 18-7 and this average energy consumption is stored among the operation history storer 18-8.To weigh function is stored among the addressable balance function memory of the policy engine 18-6 18-9.Module 18-1 also has user interface 18-10, and wherein in the function of user interface 18-10 is the temperature setting that receives the user.
Figure 19 A is the process flow diagram that is illustrated in the example process that policy engine 18-6 is carried out during the Autonomous Control.Initiate in the Autonomous Control of being come self-controller 11-0 under the situation of signal triggering, in step 19-1, policy engine 18-6 reads strategy from policy store 18-5.As stated, this strategy comprises that the energy of 0.5kWh is directed against target temperature 25 degree that air-conditioning 11-1 has produced to controller 11-0 in order to come to save altogether at least through air-conditioning 11-1 and 11-2.In step 19-2, energy engine 18-6 provides this target temperature to conditioner 18-7, wherein conditioner 18-7 carry out work with keep room temperature be 25 the degree.Replace target temperature (25 degree), the strategy that receives can comprise the energy fluence (0kWh) that will save.Shown in Figure 15 the going up of balance function memory 18-9 storage shown, because this table is to be designed by air-conditioning 11-1.If the strategy that receives comprises the energy fluence (0kWh) that will save, then policy engine 18-6 uses the balance function that is stored among the storer 18-9 to convert this energy fluence that will save to room temperature 25 degree.According to the operation history data that is stored among the storer 18-9, policy engine 18-6 also finds and keeps room temperature is the required energy fluences of 25 degree.The energy fluence that is found is conditioner 18-7 consumable upper energy limit amount in next 24 hours time period.
To keep under the situation that room temperature is 25 degree, in step 19-3, whether policy engine 18-6 judges is provided with new temperature to conditioner 18-7 in conditioner 18-7 work.Because it is dissatisfied to room temperature that user's temperature setting shows the user, therefore be looked at as complaint from the user.Yet when being provided with new temperature, how uncertain this new temperature will influence the energy consumption of conditioner 18-7.In step 19-4, policy engine 18-6 accepts user's temperature setting and newly-installed temperature is provided to conditioner 18-7, and wherein conditioner 18-7 work now is newly-installed temperature to keep room temperature.
During Autonomous Control; Policy engine 18-6 keeps watch on and is stored in the energy that the conditioner 18-7 among the historical memory 18-8 is consumed, and the gross energy that prediction conditioner 18-7 might consume before 24 hours time period finishes in step 19-5.According to the different operation environment, it is that the required energy fluence of 25 degree possibly be different from and kept the required energy fluence of same room temperature yesterday that conditioner 18-7 keeps room temperature today.In 24 hours, might consume the energy (step 19-6) that is significantly less than the upper energy limit amount if policy engine 18-6 dopes conditioner, then policy engine 18-6 indication New Policy requester 18-11 is to controller 11-0 request New Policy (step 19-7).Then, New Policy requester 18-11 is sent to controller 11-0 with request signal (Fig. 3) via transmitter 18-12.When 24 hours time period finishes, might consume the energy (step 19-8) more than the upper energy limit amount if policy engine 18-6 dopes conditioner 18-7, then policy engine 18-6 will move to the step 19-9 of Figure 19 B.On the contrary, policy engine will be back to step 19-3.
In Figure 19 B, in step 19-9, policy engine 18-6 notes the preference of user to operation.The user of requirement air-conditioning 11-1 registered user's preference power-save operation in advance still is in order to realize the operation of higher satisfaction.The user can be registered among the controller 11-0 to the preference of operation and be included in the strategy that will be sent to air-conditioning 11-1 and carried out by air-conditioning 11-1.Alternatively, can user's preference be registered among the air-conditioning 11-1 and carry out reference when the implementation strategy by policy engine 18-6.If policy engine 18-6 finds the user preference of air-conditioning 11-1 in order to realize the operation of higher satisfaction, then this processing will be back to step 19-3.In subsequent treatment, even doping conditioner 18-7, policy engine 18-6 when 24 hours time period finishes, might consume energy more than the upper energy limit amount, policy engine 18-6 is skips steps 19-8 also.If policy engine is found the user preference power-save operation, then this policy engine confirms that new target temperature maybe should be restricted to the consumable upper energy limit amount (step 19-10) that is lower than with the energy consumption with conditioner with room temperature from the degree that 25 degree improve.In one embodiment, use following equality to confirm new target temperature.
P＝A·(T
s-T
h)·W·t
Wherein, P is at new target temperature T
sThe energy fluence that following expection will be saved, " A " are the rate of changes (" A " is approximately equal to 10%) of per 1 degree of energy consumption, T
hBe current room temperature, W is the expection average energy consumption in 24 hours, and t expected the total duration that air-conditioning is worked under new target temperature before time period of 24 hours finishes.P be consumable upper energy limit amount with conditioner 18-7 work with the situation of keeping current room temperature and finishing up to 24 hours time period under this conditioner 18-7 energy total amount of in 24 hours, predicting to consume poor.Therefore, the above equality target temperature that can make new advances.
Then, in step 19-11, policy engine 18-6 confirms the acceptable room temperature range of user.Figure 20 illustrates the example function of the relation between explanation room temperature and the satisfaction.Satisfaction is got 0～100 value.The satisfaction of on shown in Figure 15, listing in the row of right-hand member of table is to deriving according to function shown in Figure 20 from the temperature difference shown in the secondary series of the right-hand member of this table.Figure 20 also illustrates the scope of satisfaction.Shown in figure 20, be limited to 100 on this scope, and the following of this scope is limited to 80.It is peculiar that degree " 80 " is looked at as the user institute of air-conditioning 11-1, and the minimum satisfaction of expression user acceptable.Can utilize function shown in Figure 20 should the minimum satisfaction convert the highest room temperature of user's acceptable to acceptable.According to Figure 20 and according to Figure 15, satisfaction " 80 " is corresponding with room temperature 27 degree of the user's acceptable maximum temperature that is looked at as air-conditioning 11-1.Therefore, policy engine 18-6 can suppose safely and can between 25 degree and 27 degree, improve room temperature under the situation of the comfort that can not damage the user.
Policy engine 18-6 confirms that based on being stored in operation history among the operation history storer 18-8 I accepts satisfaction.Temperature setting that operation history storer 18-8 was former with the user and room temperature and satisfaction be record relatively.The temperature setting is looked at as user's complaint.If it is uncomfortable that the user feels, then this user is provided with lower or higher temperature to conditioner 18-7.Through the temperature setting before the monitoring user, policy engine 18-6 and user's satisfaction is confirmed the distribution that temperature is provided with relatively.It is observed threshold value in this distribution that I is accepted satisfaction, wherein observes a plurality of temperature settings below the threshold value at this, and observes temperature setting seldom more than the threshold value or do not observe the temperature setting at this.The user can be provided with I to controller 11-0 or air-conditioning 11-1 and accept satisfaction.Accept satisfaction if controller 11-0 is provided with I, then this I is accepted satisfaction and be included in the strategy that will be sent to air-conditioning 11-1 and realize by air-conditioning 11-1.
Return Figure 19 B, in step 19-12, policy engine 18-6 judges whether new target temperature can accepted in the temperature range.If new target temperature is higher than 27 degree, then policy engine 18-6 will indicate New Policy requester 18-11 to controller 11-0 request New Policy (step 19-7).Then, this New Policy requester is sent to controller 11-0 with request signal (Fig. 3) via transmitter 18-12.If new target temperature is equal to or less than 27 degree, then policy engine 18-6 will be back to step 19-3.
Return Figure 18, when receiver 18-3 slave controller 11-0 received command signal, module selector switch 18-4 started balance function update module 18-2.Module 18-2 has function renovator 18-13, and wherein function renovator 18-13 updates stored in the balance function among the balance function memory 18-9.In the present embodiment, the balance function of air-conditioning 11-1 is represented by shown in Figure 15 going up.Function renovator 18-13 at first upgrades converse routine, i.e. temperature (" temperature is set " row) being set and can saving the relation between the energy fluence (" can save energy " row) shown in this table.Can draw according to the following equality identical and can save energy fluence (P) with equality above use.
P＝A·(T
s-T
h)·W·t
Wherein, T
sBe temperature set (on shown in Figure 15 the table in, T
sBe 25 degree, 26 degree, 27 degree or 28 degree), T
hBe the mean value of the room temperature that conditioner 18-7 is kept in the past 24 hours, W is the average electric power of 24 hours internal consumptions in the past, and t is the total duration that uses air-conditioning in the past 24 hours.All be stored among the operation history storer 18-8 calculating all these required parameters of P.
Function renovator 18-13 also upgrades the relation between temperature (" temperature is set " row) and the satisfaction (" satisfaction " row) that is provided with shown in this table.ISO 7730 explanation PMV (Predicted Mean Vote, expection average ratings) and PPD (Predicted Percentage Dissatisfaction, the dissatisfied percent of expection) index, but and the acceptable conditions of appointment thermal comfort.Derive the function of describing temperature and being directed against the relation between the satisfaction of temperature equally according to ISO 7730.This function and is used as original balance function shown in the distribution X of Figure 21.Distribution X utilizes enquiry data to draw basically.Although original function can provide the objective satisfaction to temperature, think that original function does not reflect the comfort of the individual subscriber of air-conditioning 11-1 exactly.Temperature setting that operation history storer 18-8 was former with the user and room temperature and satisfaction be record relatively.Function renovator 18-13 analyzing stored in operation history storer 18-8 before the temperature setting, and distribution X revised so that it is to user personalization of air-conditioning 11-1.
In one embodiment, can revise, with consistent with normal distribution with mean value that the thermometer that is provided with according to the user calculates and variance to distribution X.As a result, distribution X can be corrected for distribution A, B or C shown in figure 21 similar.The mean value of distribution A is identical with the mean value of distribution X, but the variance of variance ratio distribution X is narrow.Therefore, distribution A show with the general public compare, user A only accepts narrower temperature variance scope.The mean value of the mean value of distribution B and distribution A about equally, but the variance of variance ratio distribution A is wide.User A and user B might feel the most comfortable under roughly the same temperature.But the temperature variance scope of compare with user A, user B acceptance is wideer.User C feels the most comfortable under than the high temperature of the temperature of user A and B, and only accepts very narrow temperature variance scope.Think that the revised relation that is provided with between temperature and the satisfaction has reflected that more accurately the user is to the comfort that temperature is set.Then, the balance function after function renovator 18-13 will upgrade is sent to controller 11-0 via transmitter 18-12.
